Description

Noble metal Pt nanoparticles have been considered as the most effective co-catalyst to improve the photocatalytic hydrogen production activity of TiO2. In this study, the effect of the dispersion of Pt nanoparticles on the photoactivity of TiO2 nanotubes was investigated. Compared with the samples that the co-catalyst of Pt nanoparticles agglomerated or freely dispersed, the sample with the uniformly dispersion of Pt nanoparticles showed a higher performance for photocatalytic hydrogen production. The photocatalysts were characterized systematically by TEM, BET, UV-Vis, XPS, and PL techniques, and the relationship between the structure and the photoactivity was investigated in detail. The results demonstrated that the dispersion status of Pt nanoparticles had a crucial effect on the photocatalytic activity.
